EX'TBICA-TIHG DEVICE.

Application filed august 2, 1921.- Serial No. 489,244.

1 {0 all whom it may comm m Be it known that T, JOHN hio lnrcrmon,

a citizen of the United States, residing at Peabody, in the countyoiiltlarion and ate 01' Kansas, have inventednew usei'nl Improvements in Extricating Devices, of,

which the following is aspccification.

This invention comprehends the provientricating device, in the nature of a shoe shaped to conform to the curvature Of the tire and adapted to be arranged immediately in advance oi the traction wheel of the" vehicle, the shoe having; associated therewith a chain cabie or the like to preventthewheel from slipping passes over the shoe. c

Tn carrying out the invention, T also provide the shoe with a ground enga j her arranged atone end oi the shoe and de signed to be embedded in the ground to prevent movement of the shoe with reation to the ground when the shoe is in use-tor the purpose stated.

The nature and advantages oi the invention will be better understood when the following detailed description is read in con. nection with the accompanying drawing, the invention residing in the construction, combination, and arrangement of parts as claimed.

In the drawing'iorming part of thisapplication, like numerals of reference indicate similar parts in the several views and wherein Figure l is a plan view of the shoe, showing the position of the latter with relation to one 01' the traction wheels oi the vehicle.

Fig. 9. is an edge elevation of the shoe. Fig. 3 is a sectional view taken on line 3-3 of Fig. 1.

Fig, a is a perspective view of a. modified form of the invention. 7 7

The device forming the subject matter of my invention consists of a shoe 1i). The shoe may be constructed from any suitable material and may also vary in size without cleparting from the spirit or: the invention, the shoe being elongated and curved transversely to conform to the curvature of the tire mounted upon the traction wheel 01": the vehicle. The opposed edges oi th shoe are formed withnotches 11,- the notches on one side of the shoe being; staggered with relation to the notches on the opposite side, so

that the transverse portions of the chain 12 are arranged diagonally across the shoe as Specification of Letters Patent. I E5fi;Q 1l E so, rear.

clearly illustrated, The chain 12 iswrapped 1 V .1 .aoout the shoe passing through the notches 11, so that the chain extends the shoe upon boththe upper and lower sidesthereoi. iheshoe 1s providedwith a ground on mg member 13, this member being cons1dera-bly wider than the shoe 10 and of substantrally inverted ti-shaped formation in cross section. The opposed flanges it of the ground engaging memherare adapted to be embedded intothe ground, and these flanges with the assistance of the'cross runso'f the chain along the under side oitne shoe pro hibits any movement. of Jheshoe withlrela tron to the ground when the shoe is in use, it desired, a chain, cabie or the like 15 has one end secured to he ground engaging member, extending); m the adapted to be sccurei o apost, tree or any other stationary object, and also assists in holdingthe shoe fixed in its given position upon the ground, preventing the shoe 'iirom slipping when the wheel oi the vehicle traverses the same.

in practice, the shoe is placed upon the ground directly in advance of one of the traction wheels of the vehicle in the manner illustrated in Fig. 1. T1"- the wheel is not equipped witha tire chain, a chain or any other suitable member is wrapped about the upper portion of the wheel as indicated at '17 in Fig. 2, so that when the wheel revolves, the chain 12 on the shoe prevents the wheel from slipping, thus making itpossible for the machine to move out of mud holes, ditches or the like under its own motive power;

and is preferably of a size to be conveniently carried in the tool box of the vehicle.

In F 4-, T have illustrated a modified form of the invention, wherein the shoe is indicated at 18. The shoe is elongated and curved transversely to coriorno to the curvature of the tire in the same manner as above described. The opposed edges of the shoe are provided with notches 19, the notches along one edge being staggered with relation to the notches on the opposite edge, so that the transverse runs of the chain 20 will be arranged slightly diagonally across the shoe at both the top and bottom thereof. The ends of the chain may be secured in any suitable manner, but are preferably provided with hooks to engagethe adjacent run of the chain as illustrated. This form of the inletter and vention varies from the form above described, in that it. eliminates the use of the ground engaging member. The shoe is provided With a chain,,cable orthe; lilre,;indicated at 21 which extends from one end of the shoe and is adapted to be secured to any suitable tinedoh'jech such as tree post or the like for holding the'shoe against movement with relation to the ground as the Wheel of the" vehicle traverses the shoe. The preferred term of theinvention is used identically in the same manner as describedin connection with the preferred form. f

While it is believed that from the :Eoregoing description the nature aovantages of the invention Wlll be readilv a parent I V J l J 7 esire to have it understood that l. do not limi myself to is herein shown and described and that such change may be resorted to when desired as tall Wli'lllll the soopeot What is claimed.

1. An automobile eiztricating device comprising an elongated shoe curved transversely, a chain'wrapped around the shoe and a cable having one-end secured to one end 01 the shoe for the purpose specified.

2. An automobile extricating device comprising an elongated shoe curved transversely to conform to the curvature of the tire ofthe vehicle, the opposed; edges of said shoe having spaced notches, with the notches ,eonooe along one'edgestaggered with relation to the notches on the opposite edge a chain the opposed edges of the shoe having notches for the reception or" the chain, and a ground engaging member carried by one end of the r shoe and designed to be embedded in the ground for the purpose specified.

4:. Anautomobile extricating device coinprising an elongatedlshoe curved to conform to the curvature of the tire oi the vehicle;-

a chain Wrapped transversely of the shoe throughout its length the opposed'edg'es of the shoe having notches receiving said chain, the notches at one side being disposed :in

5 staggered relation to the notches at the opposite side, a ground engagingnieniherof substantially inverted d-sl'iaped formation in cross section adapted jtobe embedded in the ground, said member being considerably Wider than said shoe and a cable extended from said groundengaging member for the purpose specified.

In testimony whereof l ailix my signature.
